B. The parties hereto desire to modify the Lease in certain respects.

NOW, THEREFORE, in consideration of the promises and mutual covenants hereinafter contained, the parties hereto modify said Lease as follows:

1. DEFINITIONS. Except as otherwise provided in this Second Amendment, all defined terms contained in this Second Amendment shall, for the purposes hereof, have the same meaning ascribed to them in the Lease.

2. BACKUP GENERATOR. As of the date hereof, the following Article 51 BACKUP GENERATOR shall be deemed added to and made a part of the Lease:

51. BACKUP GENERATOR

(a) Within sixty (60) days after Landlord accepts in writing at the Building delivery of both Backup Generators (hereinafter defined) from the supplier of the Backup Generators, Landlord, at Tenant’s sole cost and expense, shall install in the area shown on Schedule A attached hereto and made a part hereof two (2) 1500KW auto transfer diesel backup generators (“Backup Generators”) in accordance with plans attached to the Second Amendment as Schedule B and made a part thereof. Landlord will order the Backup Generators within five (5) days after Landlord receives from Tenant an amount equal to the deposit required by the supplier of the Backup Generators. Tenant shall give Landlord a check for that deposit payable to Landlord within five (5) days after Landlord’s demand therefor. Upon placement of the order, Landlord, at Tenant’s expense, shall commence pre- installation work (i.e. site preparation, wiring, etc.) so the installation is completed promptly after delivery of the Backup Generators to the Building. Landlord shall obtain, at Tenant’s sole cost and expense, all necessary governmental approvals and permits relating to the initial installation and initial operation of both Backup Generators. Tenant, at its expense, shall thereafter keep current said approvals and permits and give Landlord true and complete original counterparts of all updated permits and approvals relating to the installation and operation of the two (2) Backup Generators within thirty (30) days after Tenant receives any such updated permit or approval.

(b) Within thirty (30) days after Landlord’s demand, Tenant shall furnish Landlord with any information regarding either or both Backup Generators and/or its (their) installation that Landlord may request. Tenant agrees to promptly comply with and strictly abide by, at its sole expense, any rules and regulations that Landlord may reasonably promulgate in connection with the installation, operation, repair, maintenance, replacement, relocation, concealment and/or removal of either or both Backup Generators. Tenant agrees to perform all repairs, maintenance, replacements, relocations (only if required in writing by Landlord), concealment and the removal (only if required in writing by Landlord) of either or both Backup Generators pursuant to Landlord’s rules and regulations and in a manner

that is compatible with the appearance and character of the corporate center of which the Building forms a part. Tenant covenants that neither Backup Generator shall interfere with the rights, health or welfare of any person or tenant. Tenant agrees that Landlord may install and operate, and may permit the installation and operation by others of, additional generators anywhere in the Development so long as the installation and operation of such additional generators do not materially and adversely interfere with the operation of the Backup Generators. Landlord shall in no event be responsible if, for any reason whatsoever (except as a direct result of Landlord’s negligence), either or both of Tenant’s Backup Generators do not perform to the expectations of Tenant. Landlord may reduce, at its sole option, the seven (7) parking space ratio referenced in Sections l.(p) and 36. (b) of the Lease to reflect the number of parking spaces lost as a result of the placement of both Backup Generators.

(c) Once Tenant has paid Landlord in full for all amounts due Landlord under Section 51. (a) hereof, then, the Backup Generators shall constitute trade fixtures and shall fall within the purview of Paragraph 8. (d) (iii) of the Lease. Tenant shall, by no later than thirty (30) days after the expiration or earlier termination of the Lease and at Tenant’s expense, remove both of the Backup Generators and restore any damage or injury caused by the removal of said Backup Generators. Failure to strictly comply with the immediately preceding sentence by Tenant shall constitute a holding over of the Premises by Tenant until such time as both of the Backup Generators are removed and any damage or injury caused by such removal is restored. Tenant, at its expense, shall exercise best efforts to complete its removal and restoration work sooner than the date falling thirty (30) days after the expiration or earlier termination of the Lease. If Tenant fails to strictly comply with the second (2nd) sentence of this Section 51.(c), then, Landlord, at its sole option, may, at Tenant’s expense, (1) remove either or both of the Backup Generators, (2) keep either or both Backup Generators without compensation to Tenant, (3) discard either or both of the Backup Generators at Tenant’s sole risk and with Tenant assuming all liability and/or (4) restore any damage or injury that either or both of said Backup Generators or the removal thereof may have caused. Tenant hereby releases Landlord from, and, upon Landlord’s demand, shall defend, indemnify and hold Landlord harmless against any liabilities and expenses that may arise with regard to either or both of said Backup Generators, except for such liabilities and expenses that arise as a direct result of Landlord’s negligence. Furthermore, in connection with both Backup Generators, Tenant shall procure and maintain general liability and property damage insurance in compliance with each of the requirements set forth in Sections 20. (a)-(b) of the Lease. All references in this Article 51 to “Backup Generator” shall include all wiring,

cabling, fuse boxes, transformers and other ancillary and related equipment connecting the Backup Generator to the Premises. Any cost or expense owed by Tenant to Landlord under this Article 51 shall constitute additional rent under the Lease and shall be due from Tenant to Landlord within thirty (30) days after Tenant receives written demand therefor.

3. NO BROKER. Tenant covenants, represents and warrants that Tenant has had no dealing or communications with any broker or agent in connection with the consummation of this Second Amendment and Tenant covenants and agrees to pay, defend, hold harmless and indemnify Landlord and its directors, officers, partners and their affiliates and/or subsidiaries from and against any and all costs, expenses, including attorney’s fees (prior to settlement, at trial or on appeal), court costs and disbursements or liability for any commission or other compensation claimed by any broker or agent with respect to this Second Amendment.

4. LEASE RATIFICATION. Except as modified by this Second Amendment and the instruments referenced in WHEREAS clause A. hereof, the Lease, and all covenants, agreements, terms and conditions thereof, shall remain in full force and effect and is hereby in all respects ratified and confirmed.

5. AUTHORITY. Landlord and Tenant represent that the undersigned representatives of Landlord and Tenant respectively have been duly authorized on behalf of their respective parties to enter into this Second Amendment in accordance with the terms, covenants and conditions set forth herein, and upon either party’s request, the other party shall deliver evidence, in form and substance reasonably satisfactory to the requesting party, to the foregoing effect.

7. NON-BINDING DRAFT, The mailing or delivery of this document or any draft of this document by Landlord or its agent to Tenant, its agent or attorney shall not be deemed an offer by the Landlord on the terms set forth in this document or draft, and this document or draft may be withdrawn or modified by Landlord or its agent at any time and for any reason.
